(Cl. 308-243) This invention relates to journal lubricators.

Proper lubrication of journals, particularly journals running on partial bearings in a journalbox of a railway car, is particularly troublesome in some instances, and it has been generally concluded that resort to waste packing in a railway journal box is responsible for many of the operational hazards such as hot boxes that have been encountered due to improper lubrication of the bearing.

The use of an absorbent, pad-like lubricator in a journal box below the journal has been proposed, and in this instance oil or like lubricant is fed by capillarity from a supply inthe bottom of a journal box on to the journal.

Such a pad may be in the form of oil-resistant, relatively resilient porous rubber such as synthetic open or closed cell neoprene foam rubber, and it has been found advantageous to encase a pad of this kind in a cover of wicking material which assures that the pad is protected against glazing over due to running of the journal on the pad. At the same time, the wicking characteristic of the cover assures a supply of lubricant absorbed in the pad to the journal. It is recognized that a journal lubricator of this kind may tend to be shifted to one side or the other of the journal box due to motion of the journal. This, of course, is a disadvantage, because the lubricator under such conditions is not centered in the bottom of the journal box where usually the lubricant is at its maximum depth, and moreover there is danger that the lubricator when shifted will be pinched between the journal and the bearing.

In a co-pending application, Serial No. 550,348, filed December 1, 1955, there is disclosed one kind of pad:

type lubricator having a wicking cover modified in such a way as to substantially inhibit the foregoing tendency of the lubricator to be shifted laterally within the box, and this particular lubricator has other advantages fully described in the aforesaid application.

There are some extreme occurrences in freight service a caused by sudden acceleration or deceleration in combination with lateral thrust, or even on curves in the road, where the journal exerts rather severe thrusts on the lubricator, and under the present invention we have found that a journal lubricator comprising a porous pad having a cover of high wicking characteristics can be prevented from following the motion of the journal under such severe conditions by stiffening opposed ends of the. cover .to afford in effect stiff end panels or sections adapted .to engage abutments on the inner side walls of the journal box so as to limit the extent to which the lubricator can be shifted by the journal, and so to do is one of the primary objects of the invention. Specifically also, we have found that by disposing a pair of such pads within a sleevelike cover, and by drawing together opposite faces 2,939,751 Patented June 7, 1960 fed uniformly thereto, and a further object of the present.

invention is a lubricator having a cover with this desirable characteristic.

Another object of the present invention is to provide in a lubricator of the foregoing kind a positive acting lock or deterrent to shifting of the lubricator axially of the journal.

Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanying drawings which, by. way, of illustration, show preferred embodiments of the present invention and the principles thereof and what we now consider to be the best mode in which we have contemplated applying these principles. Other embodiments of the invention embodying the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.

The present invention is illustrated in Fig.- l of the drawings as embodied in a journal lubricator 20 con,- structed specifically for the lubrication of a journal running in a partial bearing of a railway .car, and in Fig. 2 the lubricator 20 is shownloperatively disposed between the bottom of the journal box IE and the journal I of the railway car. Disposed in the upper section of the journal box IE is a partial bearing B of conventional construction having a bearing face BF of bearing metal on which the journal runs, and the bearing is held in place in the journal box by the usual wedge W. The journal box JB is provided interiorly with opposed stop columns SC-l and -2 that prevent axial shifting-of the bearing B, this being in accordance with .one .form of standard journal box construction. Advantage is taken of this in accordance with the present invention as will be described herein below.

Under the present invention, the lubricator 20 comprises a one piece, sleeve-like or tubular cover '21 which is ofa wicking material having substantially equal wicking rates both in a longitudinal and transverse direction, which is to say that the wicking rate orability re pass liquid by capillarity is the same in the direction or the filling threads as it 'is in the direction of the warp threads.

Theparticular weave for the-zcover 21 which achieves this advantageous characteristic .will be describedherein below.

Disposed in spaced relation within the cover 21are a pair of oil-resistant, relatively resilient porous pads 25A and 'ZSB of ;rectangtilar'.=hlocklike construction, Fig. 2, preferably of open cell neoprene sponge synthetic rubber adapted -to absorb and retain relativelyflarge quantities of lubricating-oil. Thus,:pr'ior:to installation, the lubricator ZO is drenched in oil and .allowed to absorb to :the full knowngthere are many times whenrelative'verticahmotion occurs hetween "the iournzil "J ithe journal 'box IE. When this takesplace,the-pads o'f the' lubricator 20, 25A and 25B, are compressed in the-journal box :and oil in those-*passages 26 having openings at the lower faces of the pads will be placed under pressureand oil inefiect is pumped upwardly through the dead ends oithe passages 26 -aszjets or-sprays'therebyfurnishing-the journal J with relatively largesamounts of lubricant. -Where the pads ZSXA and 25B are o f'opencell material, this takes place readilygand where :thepads ZSAnnd 25B are of closed cell type thekdea'd endsrof the passages zfi and the portions of the pad beyond are punctured or tapped to enable the foregoing pumping action-to occur effectively.

As will be appreciated from Fig. 2, the ends ofthe lubricator having the brass grommets Stland 31 will be displaced well below the collar portions of the journal.

thereby affording cleaner contact between the lubricator andthe journal. Thusywhere etfective contact with opposed sides of the journal and-ready conformance to the geometryof the bottorn of the journal boxis ofprime importance, the-stitch 213 can be-omitted as will'be apparent from -Fig. 1, and the grommets 30 and 31 alone used to separate the pads 25A "and 25B and divide the lubricator 20 into symmetrical sections. This use of the grommets alone asdividers produces channels like 2-7 and 23, 'althou'ghnot -of:the full depth of'the'channels 7/7- and 28 accompanied bystitching. Moreover, the grommets in-this-instance are displacedbelow collarportions o fthe journal It will be recognized from Fig. 2 that-it is desirable that t-he lubricator 29 remain substantially in the :position illustrated'whereat the channels '27 and i123 -t-ap the reservoir lubricant' at themajor clepth=thereofi This -is especially'true in those 'instancessvherethe level of lubricant is tending-toward--a minimum. "In ;accordance' with the present'invention, the desired centering ofthejluln icator is maintained' by-=stiffening the opposed-ends -of-the sleeve 21 in which-the pads 25A and 25B are disposed. Several different ways of accomplishing this can be-resorted toas willnow be'described, -andin each instance the-stiffened ends of the-sleeve or cover-aredlexibly unitedto the main body of the cover.

One method of= stifiening the ends of the cover =21 ;i-s by-plates 35 and 36, Fig. l, of"heavy duty fiber-boarder the like, and these end plates are secured to opposed cover flaps or extensions 38 an'd 39-at-each endofthe cover 251. Brass "retainer'bolts 40 are passed through the extended flap portions -38 and "39 ofthe cover 21 and registered openings in theend plates'-35-arrd'e36. Brass nuts 41,;Fig. 3, are used on --theends of the bolts "40 opposite the heads to 'drawrthe plates 35 =an'd 36 toward one-another-and to fasten together tightly-the'end portions '38 and 3 9-of the cover-21. Preferably, endsof' the bolts l -which extend beyond the nuts-aregroundofl. "Int-his'way theendportions as":38-and 39 ofthe opposed f-acesof-theeoverfil are stiifened.

"It was-mentioned that the-stop columns SC-LandSC-Q cooperate with the lubricator 20. Thus, as --will be --apparent iniFig. 2, any tendency'for the lubricator;29 to follow theclockwise-motion ofjthe journal l so as to shift toward a the left side of the journal box as viewed in this figure-will be limited-by-the stiifened left-hand end of the pad 21 engaging the bottom of "stop column "SC- 1. The relation is preferably such that "the stiffened ends :of the lnbricator' are of-sufiicient;dimension that inthe event the shifting-tendency ;of the'--lubrieator"20;is sufficient'to in effect cause the portion of the lubricator inwardly of the stiffened endto -be-pushed toward the stifiened end resulting-in thecondition shown in"Fig."'-3,- the stiffened end of the lubricatorwill have its outefiedge disposed'in protective-relation PR, Fig. 3, beyond the upper;face*2lU of- -the cover 21. This condition---w onld prevail"if the lubricator 20 were to be- -pushe'd or -shifted to-such1an extent that the outer ends of the plates 35 and 36 are specifically to retain in place waste packing where used for lubricating the journal. These retainers are either cast integral with the journal box or alternatively take the form of angle irons welded in place. In Fig. 4, such retainers are illustrated at RL-l and RL--2 in the welded angle iron form on opposite sides of the journal box, and these abutments can be used advantageously in the same capacity as the stop columns above described to limit creep or movement of the lubricator of the present invention in the manner described above.

It was mentioned that various alternatives may be used for stifiening the ends of the cover 21. Thus, there may be used, as shown in Figs. 5 and 5A, a channel-shaped sheet metal plate 45 fastened to the end flaps 38 and 39 of the cover to be stiffened by grommets 46, and in Figs. 6 and 6A pairs of fiberboard plates 51 and 52 corresponding to the end plates 35 and 36 mentioned above are fastened together by grommets 53. There are circumstances where either the metal or fiberboard plates may be advantageously substituted by heavy-duty webbing fastened as by stitching to the ends 38 and 39 of the cover.

In Figs. 7 and 7A, the cover 21 is stiffened at its end portions merely by a plurality of grommets 55 that are used directly to stiffen the projecting end portions 38 and 39 of the cover 21. In this connection it may be mentioned that other fastening means equivalent to such grommets may be used, but an advantage of grommets as 46, 53 and 55 is that these can be engaged by a packing hook to adjust the lubricator in or withdraw the lubricator from the journal box.

Another alternative that may be employed advantageously under certain circumstances is to immerse the projecting end portions of the cover 21 in oil resistant glue, sizing or the like serving to impregnate the interstices of the cover 21 with material that sets to a tough, hardened, impervious state. Desirably, staples can be used to supplement the stifi coating. In each instance, the stifliened ends of the lubricator as 20 constitute handles enabling insertion of the lubricator into the journal box to be accomplished with facility, and this is of particular advantage where the lubricator has been heavily loaded with lubricant prior to insertion.

In Fig. 8, a one-piece lubricator 60 is shown as comprising a sleeve cover 61 embodying a weave to be mentioned below, and in this instance a single pad such as 25A or 25B mentioned above is inserted in the cover 61. Attached to free end flaps as 62 and 63 at opposite ends of the cover 61 are pairs of stififening plates 64 and 65, fastened together in this instance by pairs of grommets 66. The lubricator embodying but one pad insert can be used for lubricating rotating journals or the like under circumstances where the conditions are not so severe as to require use of the dual pad and center channel arrangement described above.

In addition to preventing travel of the lubricator laterally within the journal box due to rotary motion of the journal I, it is advantageous also to prevent axial movement of the lubricator, and in Figs. 9 and a lubricator 70 is illustrated as embodying lock plates 71 and 72 of relatively rigid fiberboard material which serve the dual purpose of preventing lateral as well as axial shifting of the lubricator. The lubricator 70 preferably is generally of the form and construction described above in connection with the lubricator 20, and hence includes a sleeve-like cover 73, embodying a weave to be mentioned below, two oil absorbent pads as 25A and 25B described above inserted in the cover 73, and grommets 74 and 75 placed at the front and rear portions of the intermediate 5 section 73A of the cover which is stitched between the grommets 74 and 75 to draw the upper and lower faces of the cover together at this intermediate section and afford channels as 27 and 28 described above.

Several difierent forms of construction may be utilized in affording the plates 71 and 72, and in Figs. 9 and 10 this is achieved by disposing inner edge portions of the plates 71 and 72 between upper and lower relatively narrow facing plates 77 and 78. Staples are pressed through juxtaposed portions of the face plates 77 and 78 and the portion of the plate 71 or 72 that is disposed therebetween. Alternatively, a pair of symmetrically configured plates 71 and 72 can be fastened to the flap or extended end portions of the cover 73, and in this instance reinforcing plates as 77 and 78 are, of course, not necessary.

As shown in Fig. 10, the plates 71 and 72 are of a length to extend from the opposed ends of the lubricator cover 73 upwardly to and beyond the stop columns SC-1 and 80-2 in the journal box.

The outer end portions of the plates 71 and 72 are notched at 71N and 72N respectively, and this affords pairs of outwardly projecting ears 81--82 and 83- -84 at either end of the notches 71N and 72N. The notches 71N and 72N correspond in size to the width of the stop columns SC1 and SC-2 so that when the lubricator is disposed in the journal box, the ears 8182 and 8384 closely embrace the stop columns 80-1 and 80-2, thereby locking the lubricator 70 against substantial axial shifting movement. Such axial locking of the lubricator prevents contact of the lubricator with either the end collar of the journal or the fillet on the journal at the dust guard seat, and therefore the possibility of the collar or the fillet of the journal causing wear on corresponding portions of the lubricator 70 is overcome. In this connection, it commonly occurs that rotation of the collar of the journal against the front end of the bearing as B will in time create sharp edges on the collar which could have a damaging effect on the corresponding portion of the lubricator as 70 if thrust toward the rotating collar. The front and rear grommets 74 and 75 when applied to the transverse medial area of the cover of the, lubricator as shown in Fig. 9, produce relatively stiff protuberances respectively at the front and rear ends of such medial area, thereby stiffening the medial area of the cover at the front and rear ends thereof. This is also true of course of the' embodiment of the invention shown in Fig. 1. The forward one of the grommets, 75, as viewed in Fig. 9, enables the cover to be hooked by a waste hook inserted through the open front of the journal box, and the rearward one of the protuberances afiorded by the grommet 74 is engageable with the rear wall of the journal box thereby serving further to limit axial rearward movement of the lubricator in the journal box, especially in the event that the ears as 82 and 84- at the front of the lubricator as shown in Fig. 9 should be broken or somehow removed.

It will be appreciated, of course, that stop columns as $04 and SC-2 are of standard dimension, and hence the notches 71N and 72N will likewise be of such standard size. In the event that a lubricator 70 is to be disposed in a journal box having retainers as RL-l and RL-2, Fig. 4, of variable length, the lubricator can be furnished with unnotched plates 71 and 72, and prior to installation the plates 71 and 72 can be marked to indicate the required size of the notch, and the portions of the plates 71 and 72 between such markings can then be removed to afford cars at the ends of the notches for engaging the ends of the retainer ribs.

It is preferred in most instances that the cover for the lubricator be of endless tubular form, since this eliminates the necessity of stitching together free ends of the woven material to aiford the necessary sleeve-like cover. It will be appreciated that such endless construction of the cover is preferred for the foregoing reason but is not,

7 however, essential, and the cover 13.v shown nli st 9 is one wherein the cover was woven as a sheet with the free edges thereof bein brought together and stitch d a 708 to afford, the desired sleeve-like eover structure for retaining the oil absorbent pads.

Under the present invention, the cover for the lubricator in each instance is so woven as to. have substantially the same wick-ing rate in both a lateral and longitudinal direction, since this assures uniform saturation of the cover with lubricant, and; further assures that lubricant wicks through and along the cover in a uniform directional manner. The particular weave by which this is accomplished is illustrated in Figs. 11 and 12 and :in Fig. ll the manner in which the. cover material, is woven to afford. the aforementioned continuous tube is illustrated as distinguished on the other hand froma woven sheet or web such as was used for the lubricator 7.0 in Hg 9. However, regardless of whether the cover is woven as an. endless tube or in web form subsequently to be stitched at the free edges, the. arrangement .of warp, filling, and binder threads is the same as'will now be. described.

The woven cover in the present instance comprises two plys of warp threads affording an outward or face ply 590, Fig. 11, and an inner or back ply 91, and each such ply comprises warp threads 92 which are interwoven in a plain weave with filling threads 93, there being a filling pick 93F for the face ply and an associated filling pick 933 for the back ply. The two plys are connected together by a binder thread 95, and the binder thread is plain woven with respect to the filling threads, alternately between the plys. Thus, the binder thread 85 passes over and under in an alternate fashion adjacent pairs of superimposed filling threads 93F and 933. As to Fig. 11, the arrangement, as was mentioned, is one illustrating a section parallel to the warp threads on the loom, the upper two-ply portion of the .cover being woven simultaneously with the lower two-ply portion of the cover to afford an endless tubular cover. When the material is taken off the loom, the material is severed into sleeves of predetermined length corresponding to the desired size. of the Iubn'cator.

Fig. 12 is a schematic generation showing the path of the filling thread. Thus, referring to Figs. 11 and 12, it will he noted that the filling pick 93-1 is first extended through the warp threads 92 in the upper face ply 90. A second pick v195*.2 is then taken through the back ply in the lower ,set of warp threads 22. A'third pick 93 3 is then taken through the warp threads in the upper back ply, and finally a fourth pick 93-4 is extended through the warp threads in the lower face ply. It will be observed ,that thesepicks areindicated in Fig. '11.

The filling thread 93 is next shifted forwardly for the next set of four picks 93-5, 93-6, 93-7, and 93-8, occurring in the sequence described in connection with the first four picks. After the last four picks, 93-5 through 93-8, the filling thread 93 is again shifted forwardly and the cycle of the back and forth picks alternately between the upper and lower sets of face and back ply warps is repeatedasindicatcdin Fig. 12.

,It will be seen from the foregoing that under the present invention, a journal lubricator is afforded which includes a wicking cover so woven as to have substantially equal wicking rates in all directions, and the ends of the cover are provided with stiffened sections adapted to engage abutments in the opposed side Walls of the journal box so as to prevent or limit lateral shifting of the lubricator. Such stifiened sections maybe further modified to embrace the opposed ends of such abutments toprevent or limit axial shifting of the lubricator. Where such extended stiffening sections as 71 and 72 are resorted to, Fig. 10, thelength thereof is chosen in respect of the stop columns 80-1 and SC-2 so that the outer extremities of. the stilfening panels extend upward bethat engages the journal. In this connection, it should be pointed out that lubricant flowing downward from side es of the bea n in ng, a it will hen he t ota will. be r pp d in p ckets TC.
